摘要： A Packet Core Function (PCF) and method of consistently selecting a Packet Data Service Node (PDSN) from a plurality of PDSNs in a packet data network to host a data session for a Mobile Node (MN). In a first embodiment, a static lookup table in the PCF is used to associate a list of identifiers for MNs and a list of the plurality of PDSNs in the network. The PCF obtains an identifier for the MN and utilizes the lookup table and a hash function to associate the identifier for the MN with a PDSN. The PDSN is then selected by the PCF to host the data session for the MN. In another embodiment, the PCF also includes a cache timer and a cache memory that stores the identifier for the MN and the IP address of the selected PDSN for a predetermined time period following the handoff of the MN to another PCF. If the MN returns to the PCF within the predetermined period of time, the PCF reselects the same PDSN to host the data session. In another embodiment, following the initial selection of a PDSN to host the data session, the EP address of the PDSN is sent to the MN which then passes the IP address of the PDSN to any subsequent PCFs where the MN roams. A PDSN zone ID may be utilized in lieu of the fill IP address.

摘要： In a cellular telecommunications network, a method and system for performing dormant hand-off for a dormant Mobile Node (MN) between a source packet zone an a target packet zone, when the MN still has an active A10 and Point-to Point Protocol (PPP) connection in the target packet zone. According to the method, when handed-off, the MN issues an origination request with a Data Ready to Sent (DRS) parameter set to zero for the target Base Station Controller (BSC-T) which responsive to the request further sends an A9-setup-A8 registration request to a target Packet Control Function (PCF-T). The PCF-T then sends an A-11 Registration Request message to a Packet Data Service Node (PDSN-T) of the target packet zone. Responsive to the receipt of the Registration request, the PDSN-T sends an agent advertisement message to the MN and initiates the Mobile IP (MIP) registration procedure, and the MN can register the care-of-address information relating to the new serving PDSN, the PDSN-T, with its Home Agent (HA). According to another embodiment, the same method is to be used for performing a hand-off of the dormant MN to the target packet zone, when the MN, before issuing the origination request, demands the activation of a packet data session.
摘要翻译：在蜂窝电信网络中，一种方法和系统，用于当MN仍然具有活动A 10和点到点协议时，在源分组区域与目标分组区域之间为休眠移动节点（MN）执行休眠切换（PPP）连接。根据该方法，当切换时，MN向目标基站控制器（BSC-T）发送数据就绪发送（DRS）参数设置为零的发起请求，BSC-T响应于该请求进一步发送A 9 - 对目标分组控制功能（PCF-T）的8注册请求。 PCF-T然后向目标分组区域的分组数据服务节点（PDSN-T）发送A-11注册请求消息。响应于接收注册请求，PDSN-T向MN发送代理通告消息，并发起移动IP（MIP）注册过程，MN可以注册与新服务PDSN有关的转交地址信息，PDSN-T与其归属代理（HA）。根据另一个实施例，当MN发出发起请求之前要求激活分组数据会话时，相同的方法将用于执行休眠MN到目标分组区的切换。

摘要： A system and method for optimizing the use of packet-resources by releasing a hanging packet-data connection when a Mobile Station (MS) performs a power-down while involved in a dormant packet-data session. A Base Station Controller (BSC) sends a message to a Mobile Switching Center (MSC) indicating that the MS has powered down. The MSC determines that the packet-data session is dormant, and sends an instruction to the BSC in a class-0 connectionless transaction to release network resources associated with the packet-data session. The BSC then sends an instruction to a Packet Control Function (PCF) to tear down the associated resources, and the packet-data connection is released by a Packet Data Service Node (PDSN) in response to the tearing down of the resources by the PCF.
